Specification of Letters Patent." Patented 'N131'. 191.2-

' Application led July 10, 1911. Serial No. 637,852.

To 'all whom it may concern:

Be it known that I, GARnIsoN C. THAYER,

a citizen of the United States,.residing at Bartlesville, in the countyof' "Washington 5 and State of Oklahoma, have invented certain new andusefuhlmprovements in Reim forced Axles; and I. do declare the followingto be a full, clear, and exact description of they. invention, such. aswill enable others skilled in the art to which it appertains to make anduse the saine.

This invention relates to improvements in vehicle axles.

' Theobject of the invention'is to provide a simply constructed, strongand cheaply manufactured axle. With this and other objects in view, theinvention consistsof certain novel features of construction, 20 ment ofparts as will be more fully described -and particularly pointed out inthe append- In the accompanying drawings: Figure 1 represents a side.elevation of an axle constructed in accordance with this invention;Fig-2 is a top plan view thereof; Fig. 3V isa longitudinal horizontalsection taken on the line 3-3 of Fig. l; Fig. 4 is a longitudinalvertical section taken on the .line 1r-tof Fig. 30 2; Fig. 5 is atransverse section taken on the line 5-'5 of Fig. 3 and'looking in thedirection of the arrows; Fig. 6 is a detail perspective view of aportion of one of the reinforcing plates; Fig.. 7 is a similar view of aslightly modified form of plate.

. In the embodiment illustrated an axle is shown lcomposed of a metalcore and an outer Wooden casing or shell rigidly connected, the corecomprising two metal plates 3 and 4, said plates being secured togetherby, transversely arranged bolts as 5. Any desired number of bolts may beemployed .for securely clamping the members to- :gether. These platesare tapered toward their opposite ends as shown to provide for theapplication of the axle skeins G thereto.

' The plates 1 and 2 are provided with a .plurality of registeringoutwardly bulged transversely extending semi-circular grooves as-7which, -when the plates are assembled formbolt holes for the passage ofthe bolts which connect the axle to the bolster, the upper edges of saidplates being recessed above the grooved portion 7 to receive and ,housethe-headsof the bolts which secure the combination and arrange.

..1' and 2fand the shell two outer wooden plates axle to the bolster.The opposite ends of` these plates l and 2V are also provided withlongitudinallye extending semi-cylindrical grooves as 8 which registerwith each other to form bores which are screw-threaded on their innerAfaces to receive lag screws as 9 for securing the skeins 6 to the axle.Fer

rules, as 10 are applied to the ends of the axle, fitting in recessesformed on the outer Vfaces of the wooden members thereof and aredesigned to prevent the spreading of the axle ends when the lag screws 9are inserted. The inner end of said ferrules abut against shoulders 8formed near the ends of the plates l and 2.

The metal core formed by the plates 1 and 2 provides a very stronglightweight axle which will carry two-thirds more weight than any woodenaxle, and will cost but atrifle more. -It is preferable that the innerreinforcing core be'made of two plates in order that the bolt holes forconnecting it with the bolster may be readily formed therein, but asingle plate may be employed if desiredsuch as is shown at 11 in Fig. 7.This plate 11 is provided with a plurality of4 longitudinally extendinglongitudinally spaced slits as l2 arranged between the edges of theplate and the.upper portion of theplate adjacent each slit is bent inone direc tion and the lower portion in the opposite direction toprovide bolt receiving members as shown in Fig. 7.

From thepforeging description taken in connection with the accompanyingdrawings, thc construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion,

Aand the minor` details of construction may be resorted to without.departing from the principle or sacrificing any of the advantages -ofthe invention asdefned in the appended claim.

I claim as my invention:

An axle comprising a wooden shell having a metal core 'extending fromend to end thereof and composed of two .correspond-.v

ingly shaped plates arranged in contactt with each other and havingtransverselyl extending registering grooves in their faces between theirends forming bolt receiving apertures, the ends of saidplates havinglongitudinally extending grooves in their inner faces,

tering with those in the other and threaded the grooves in one plateregis-A to form sockets 'to receive skein securing' screws, ferrulesencircling'tlie ends of said shell to bind it to' said core, means forsecuring said core and shell together between 5 their ends, skeins onthe ends of said axle and lag screws passing through said skeinsandengagng the sockets in said core.

In testimony whereof I have hereimto s et my hand in presence of twosubscrlbing Witnesses.
